This is a real easy song, but a fun one.
The premise for the whole song is this riff:
Am x4 Dm x4
e--------------------------------------------------------------------------|
B--------------------------------------------------------------------------|
G--------------------------------------------------------------------------|
D--------------------------3-5-3-------------------------------------------|
A----------3-5-3------5-5-5------------------------------------------------|
E-----5-5-5----------------------------------------------------------------|
Then the chorus just goes C5-A5-D5
Then it returns to the main riff.
That's pretty much it. Not much going on so its a real fun song just to jam to. Have fun!
